"It seems unfinished -- my career," she said on the Joe Rogan Podcast. "There's more left to do. I don't feel like I'm done yet. With the Olympics, you win an Olympic gold medal and you're done. With the UFC, when am I done?"

"With the UFC, when am I done?"

Ronda Rousey became the first American to win an Olympic medal in women's judo when she took bronze at the 2008 Games in Beijing. She retired from judo following this event, but found her way into MMA three years later.

She won the Strikeforce Bantamweight Championship in her fifth pro fight, a title that later became the UFC Women's Bantamweight Championship in 2012. She held that belt through six consecutive defenses (the standing record for the longest title fight finish streak).

Despite all of that, Rousey says her career is still missing something. According to her however, one fight that would help her career feel "finalized" would be a match-up with Invicta featherweight champion Cris "Cyborg" Justino.

When asked if that fight would give her career some closure, Rousey replied that it "definitely would."

"If she never steps up, I'll know," she said. "I'll probably go on a little longer waiting for her [to drop in weight], see if she shows up sooner rather than later. I don't know how much longer I'd go."

Rousey has previously expressed doubts that #Cyborg would make the 135 cut, and Cyborg has already said she can not. On more than one occasion, Cyborg has asked Rousey to meet her at 140 pounds for a super fight. To date Rousey has not accepted this challenge.

Cyborg has gone 2-0 in her two UFC outings, both at a 140 pound catchweight. She still holds the Invicta featherweight title and has gone undefeated for over 10 years.

Rousey has not fought inside the Octagon since her loss to Holly Holm at UFC 193. She will face current champion, Amanda Nunes, at #UFC207 for what could be her last fight.
